MUD-LUG FOR TRACTION-WHEELS.

Specification 01" Letters Patent.

lfatcnted July 8, 1913.

Application filed June 20, 1912. Serial No. 704;,889.

To all whom, it may concern Be it known that I, litnoonrn Sonwnsmenu, acitizen of the United States, resicl .ing at Plentywood, in the countyof Valley, tats of Montana, have invented certain new d usefulimprovements in Mud-Lugs for "action il heels; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

'lheiprcsent invention consists in a new and improved traction wheel andmore particularly to a novel and improved anti-slipoing device thereforwhereby when the wheels become sunken or embedded in the ground.surface, especially in soft soil and bog holes, the said element willthus operate to aii'ord proper traction and permit the w ionnent oil theengine or machine.

7 if :sfll y the invention resides in a u rude and strong mud lug ofnovel con: struction and rigidly attached to the rim ot a traction wheelinwardly of the periphery thereof and interiorly connected by a rim ortire to brace the same when used.

With. the above and other objects in view, this invention resides in thenovel features oi. construction, formations, combinations andarrangements of parts to be hereinafter moi-ci'ully described, claimedand illustrated in the accompanying drawing, in which:-

Figure 1 is a side elevation of a tragmentary portion of a tractionwheel having my improved traction means or extension mud lug securedthereto. Fig. 2 an end elevation of the device. Fig. 8 is an enlargedtuausverse sectional view taken through the traction wheel and one ofthe lugs. Fig. l is a horizontal sectional view of the parts illustratedin Fig. Fig. IS a detail perspective view of fastenlng washer employedwith one of the lugs. Fig. 13 is a similar View of a supplementary lugattached to one of the extension lugs.

ln illustrating the practical application of the invention there isshown a fragmentary portion of a traction wheel indicated by the numeral10, to the rim portion 11 of which 'a plurality of spaced laterallyextending mud lugs 12 are secured. These lugs are spaced at suitabledistances around the periphery of the tire inwardly of which they aresecured through the medium of bolts 13 which contact with the inner faceof the rim and which. have their projected or outer extremitiesllattenml out as shown at 14 and provided with a suitable number ofapertures lor riveting the same to the outer portion of the lug 12 asillustrated at 15 while the opposite end of the bolt is threaded andextends beyond the opposite edge of the rim where it smwured to the rimtlu'ough the medium of a washer lo'engaged on the boltand having aninwardly directed portion or edge 17 forming a hook to engage the peripheral face of the rim and also serve us an anti-slipping means whenretained in position by means of a binding nut 18.

As illustrated, the extension lug 12 is shown as composed of a hollowrectangular section of metal but I wish to have it understood that I mayemploy any other shape as fairly falls within the scope of the presentinvention as claimed, and the inner end of each lug is beveled as shownat 19 to assist in the proper securing of the bolt 13 thereto withoutdecreasing the usefulness of the lugs. Tn order to further hold the lugsin position, a bolt 20 is engaged through each lug adjacent its innerportion, in a radial direction with respect to the wheel and has itsouter end bent against the periphery of the rim as shown at 21 to form aSllhStttlltll llly Lshapod clamping member secured in position by a nut22 engaged on the threaded cud oi the bolt and in contact with thelllllQl.fllC0 of the rim or tire 20. By this means lateral displacementof the lugs is prevented and the bent portions of the washers 16 and thebolts 20 greatly as sist in securing proper traction.

The extension lugs 12 are further provided with cone-shapedanti-slipping members 01 supplementary lugs 23 having threaded stems 2i;engaged therethrough near their outer ends and secured by binding nuts25 while all of the main or primary lugs 12 are connected by the rim ortire 26 which is secured in position by the nuts 22 and 25 respectivelyso as to brace the lugs in their operation. Thus, it will be evidentthat if the traction wheel or rim thereof becomes sunken or embedded inthe ground, the main and supplementary lugs will engage the ground andprevent further slipping whercby increased traction is provided to causethe advancement of the engine or machine whereas only the rim 11contacts with the. ground surface at other times.

Having thus fully described this invention what I claim as new anddesire to protect by Letters Patent, is

1. The combination With the rim of a wheel; of extended lugs arranged ats aced distances therearound, ea'c h lug embodying a bolt transverselycontacting with the rim, means at one end of the bolt for anchoring thesameto' the rim, an extension carried by the bolt and projecting beyondthe rim, clamping members connecting the bolt and extension member tothe rim, a supplementary rim also attached thereby to the extenv sionmembers and rim first mentioned and fastening means independentlyconnecting the supplementary rim and extension members to formantislipping means.

2. The combination With atraction Wheel; of an extension rim of lesserdiameter than said traction Wheel and means for securing said rim to thewheel, said means comprising extension lugs, bolts secured to theextension lugs and engaging transversely of the inner face of the wheelrim portion, securing members engaged through the bolts at one end andthe adjacent portions of the lugs and additional securing members engaged on the other ends of the bolts, all of the securing members beingthe periphery of the wheel.

3. In a mud lug for traction engine wheels, a bolt having a flattenedportion, a hollow extension member secured to the bolt at its flattenedportion, a Washer on the RUDOLPH soinwssrnesn.
